Title: Formation of sheet material using hydroentanglement
Inventor: BEVAN CHRISTOPHER GRAHAM
IPC: D04H1/492
Filed: 2001-06-04
Abstract: Artificial leather sheet material is made by hydroentanglement of waste leather fibres. A web (28) of the fibres is advanced on a porous belt (8, 9) high pressure water jet heads (13) in a number of successive hydroentanglement steps.

Patent CA-2424077-A1 (CA)
Inventor: UNDERBRINK CHRISTOPHER M
IPC: A61B8/00
Filed: 2001-10-15
Abstract: L'invention concerne des diagnostics et des analyses ultrasoniques de tissu cellulaire. Une sonde ultrasonique se déplace sur le tissu cellulaire à une vitesse uniforme que l'on peut synchroniser avec la vitesse de capture d'image de l'analyseur ultrasonique afin de réaliser un ensemble complet et contigu d'images analysées du tissu. On peut maintenir la sonde dans une seule position lorsqu'on la déplace sur le tissu ou on peut la régler dynamiquement lors de l'analyse afin d'obtenir un contact optimal avec le tissu analysé. Les données d'image sont alors capturées et converties à un format qui peut se stocker facilement et qui est également compatible avec une visionneuse. Celle-ci permet de lire des images analysées de manière optimale pour le dépistage de cancers et d'autres anomalies. Une fonction de localisation permet à l'utilisateur de sélectionner un point présentant un intérêt sur une image individuelle analysée et de choisir un autre point de référence connu. La fonction calcule et donne la distance du point de référence au point présentant un intérêt en trois dimensions. Le système peut servir pour quasiment tous les types de tissu mais peut également être optimisé pour le dépistage de cancers du sein. On peut placer un élément de densité différente sur le mamelon afin de fournir un point de référence visible sur les images analysées. On peut recouvrir le sein d'un tissu composé de manière à maintenir le sein en place et réduire les erreurs d'analyse ultrasonique ainsi que le maintien de l'élément en place. La fonction de localisation susmentionnée se sert du mamelon comme d'un point de référence à partir duquel on peut mesurer tout cancer ou autre anomalie dépistés.

Title: Prevision et detection du debut de crises d'epilepsie
Inventor: ECHAUZ JAVIER RAMON
IPC: A61B5/04
Filed: 2001-10-19
Abstract: L'invention concerne un procédé et un appareil de prédiction et de détection de l'apparition de crises d'épilepsie dans un cadre probabiliste à résolutions multiples unifié, permettant à une partie du dispositif de fournir automatiquement une progression de thérapies multiples, allant de la thérapie bénigne à la thérapie agressive comme les probabilités de crise. En se fondant sur les nouveaux algorithmes intelligents de calcul, une fonction de probabilité postérieure réaliste P(ST<X) représentant la probabilité d'une ou plusieurs crises débutant dans les T prochaines minutes, des observations x données, dérivées d'un électroencéphalogramme (EEG) intracrânien ou d'autres signaux, est synthétisée de façon périodique pour plusieurs horizons prévisionnels. Lorsqu'elles sont couplées de façon optimale à des limites déterminées pour une activation d'alarme ou le début d'une thérapie, les probabilités ainsi définies offre une localisation du temps anticipée des événements dans un réseau de type logarithmique synergique des résolutions de temps, contournant ainsi de façon efficace la performance par opposition à l'analyse prédiction/horizon des systèmes de résolution unique. Les échelles de temps de prévision longues ou courtes sont faites pour correspondre respectivement aux thérapies bénignes et agressives. L'imminence des crises sert à moduler le dosage ainsi que d'autres paramètres de traitement durant un contrôle en boucle ouverte ou un contrôle rétroactif des crises une fois l'activation lancée. Une détection de l'apparition d'une crise rapide est unifiée dans le cadre comme une forme dégénérée de la prédiction au niveau de l'horizon de temps le plus court, voire même négatif. Le dispositif doit apprendre afin de trouver la prédiction de probabilité et des stratégies de contrôle qui pourront augmenter la qualité de vie du patient dans le temps. Un indice de la qualité de vie (QOLI) est utilisé en tant que guide global dans l'optimisation des caractéristiques de signal spécifiques au patient, dans la logique de décision d'activation de thérapie multiple et afin de mettre par écrit les progrès des patients, s'il y en a.

IPC: A23L3/18
Filed: 2002-03-27
Abstract: A method and an apparatus in form of a disinfecting apparatus comprising a steam device for combatting germs on the surface of products, in particular of food products. The apparatus employs a combination of steam and ultrasound to kill germs on the surface of a product which is conveyed past the steam device.

Title: Hydraulically balanced reciprocating pulser valve for mud pulse telemetry
Inventor: ROUATBI CEDRIC
IPC: E21B47/18
Filed: 2002-03-13
Abstract: A reciprocating pulser system for generating pressure fluctuations in a flowing drilling fluid comprising a reciprocating poppet and a stationary valve assembly with axial flow passages. The poppet reciprocates in close proximity to the valve assembly, at least partially blocking the flow through the valve assembly and generating oscillating pressure pulses. The poppet passes through two zero speed positions during each cycle, enabling rapid changes in signal phase, frequency, and/or amplitude thereby facilitating enhanced data encoding. The poppet is driven by a linear electric motor disposed in a lubricant filled housing. In one embodiment, the housing to shaft seal is a flexible bellows. In one embodiment, a force balance spring is used to essentially offset the hydraulic flow forces on the poppet. In one embodiment, a bypass poppet is used to adjust the differential pressure across the valve assembly.
